SUMMARY: Investigators at seven sites nationwide are recruiting 118 people with progressive forms of MS for a clinical trial testing whether the oral antioxidant lipoic acid improves function significantly more than inactive placebo. The study sites are in Birmingham (AL), Burlington (VT), Portland (OR), Salt Lake City (UT), Seattle (WA), and Washington DC. The study will involve seven site visits. The study is funded by the National MS Society and the U.S. Department of Veterans Affairs.
: Antioxidants are natural or manmade substances found in many foods. Antioxidants block the action of “free radicals,” which are normal by-products of bodily processes that may cause tissue injury and turn on immune attacks in MS. In a study
of 51 people with secondary progressive MS, the oral antioxidant lipoic acid was shown to reduce the rate of brain tissue loss compared to placebo. Now a larger study is needed to further study the potential benefits and safety of lipoic acid in progressive MS.
Eligibility and Details
: Participants are individuals over the age of 18 who have secondary or primary progressive MS, are able to walk with or without a walking aid, and are able to undergo MRI scans of the brain. Further enrollment criteria are available from the contacts below.
Fifty-nine participants are being randomly assigned to receive oral lipoic acid, and 59 are receiving inactive placebo for 24 months. The study involves seven office visits. The primary outcome being measured is the change on a test that measures mobility and leg function. Other outcomes include change in brain tissue volume loss, falls, and overall safety.
